Description

79Û1lr66-8 10 15 20 25 30 35 simple and reliable locking device. The which characterizes the invention is apparent from the following Claims The invention will be described in more detail below with reference to display to attached drawing, where Figure 1a shows a vertical section and Figure 1b a horizontal section of a locking device according to the invention in position, in which the locking device holds all of them in a magazine existing containers, and Figures 2a and b show in a corresponding section the locking device in position when the lowest container in the magazine extracted from the magazine. Q Fig. 1 shows a wall 1 of a magazine, in which a number container 2 are stacked on top of each other. The inside dimensions of the magazine is slightly larger than the outer dimensions of the containers and the shape is the same, for example rectangular or round. The containers are pre- seen with a collar 3, bead or similar. At that, such as shown, vertically arranging the lower part of the magazine is the exemplary The locking device according to the invention, meant denoted by 4, attached in any suitable manner. Blocking the device consists of a storage device arranged fixedly to the magazine. body 5, as illustrated in the form of a plate, and a barrier body 6, which is rotatably arranged around a bearing body 5 and the locking body 6 through shaft 7, which is substantially parallel to the magazine wall 1. The locking body 6 is designed with a curved surface 8, which as shown is bounded by a curved edge 9. This curved surface and edge extends from the the position of the container collar at an acute angle re- lative wall 1 to gradually merge into an increasingly with the wall 1 parallel direction. The edge 9 can be said in mainly proceed according to a helix. Furthermore, the barrier the body 6 formed with an upper horizontal surface 10. A coil spring 11 is arranged around the shaft 7 and is in the end 12 and 13 attached to the bearing body 5 and the locking body 6, 10 15 20 25 7901466-8 The curved surface 8 with the edge 9 is designed so that when extended of the bottom container, the collar sliding along a sliding surface created by the surface 8 or the edge 9, the barrier body 6 to rotate about the vertical axis 7. Thereby the spring 11 arranged around the shaft 7 will be tensioned.

By sliding surface is meant the surface or line along which the collar 3 and the locking body 6 are in contact with each other during sliding.

Fig. 2 shows the position of the locking body 6 after the complete rotation locking mode. The upper horizontal surface 10 has been given such a design that it is brought under by twisting the collar of the second lowest container, and this movement of the surface 10 is completely horizontal. The curvature of the curved the surface 8 can be adjusted so that the rotation of the surface 10 takes place with desired speed depending on the vertical distance between the collar na i stapeln. Track devices with varying steep curvature of the curved surface can be made easily replaceable, whereby the magazine is extended to such an extent that containers with different collar designs and thereby different values bare distances between the containers in the stack can be used in one and the same magazine.

As soon as the collar of the bottom container at the time of extraction has left touching the curved surface, the spring ll will rotate the locking means back from the locking position according to figure 2 to normal position according to Fig. 1.

The invention is of course not limited to those described above and exemplary embodiments shown in the drawing but can be varied in a number of ways within the scope of the appended claims.

For example, the spring can be designed and arranged on something else way.

Claims (3)

7901466-8 PATEX REQUIREMENTS: A locking device at a dispensing magazine for containers which can be stacked in a different manner with an outwardly directed collar, bead or the like, wherein the locking device is located at the dispensing opening of the magazine for the containers and comprises a locking body, which has two separate locking surfaces. of all containers present in the magazine in a rest position and constitutes a sliding surface for the collar of the outermost container at its extension, the sliding surface being displaced outwards across the discharge direction of the containers during the extraction, and the second locking surface is arranged to slide outwards is displaced inwards inside the collar of the second outermost container before it reaches the second locking surface, the locking body being provided with a spring member, against whose action the locking surfaces are displaced and which after the outer container has left the sliding surface returns the locking body 1 1 to the rest position, indicate that the locking body '(6) is rotatably mounted at a bearing body (5) located laterally in the discharge direction by means of a rotation shaft (7) extending substantially parallel to the discharge direction, and that said slide surface (8,9) initially extends at an acute angle to the discharge direction so as to gradually transition in an increasingly parallel direction with the output direction. Blocking device according to claim 1, characterized in that said second surface (10) extends substantially perpendicular to the discharge direction. Locking device according to claim 1 or 2, characterized in that said spring means (11) consist of a helical spring arranged around the axis of rotation (7) having its ends (12, 13) attached to the bearing body (5). resp. the locking body (6).
